FFP vs SFP: which focal plane should you buy?

Plain-English guide · Updated 2026-07-03

Quick answer: in a first focal plane (FFP) scope the reticle grows and shrinks with the image as you zoom, so its holdover and ranging marks stay accurate at every magnification. In a second focal plane (SFP) scope the reticle stays the same visual size at all zooms, so its marks are only accurate at one magnification (usually the highest). Choose FFP for long-range and precision shooting where you hold and dial at changing distances; choose SFP for hunting and fixed-distance shooting, where it is simpler, cheaper and always easy to see.

FFP vs SFP reticle behavior as magnification changes Four scope views. In FFP the reticle grows with the target from 3x to 9x, so holdover marks stay true. In SFP the reticle stays the same size while the target grows, so marks are only true at max zoom. FFP (first focal plane) SFP (second focal plane) 3x 9x Reticle scales with the image: marks true at ANY zoom Reticle stays the same: marks true only at max zoom
How the same reticle behaves from 3x to 9x in an FFP vs an SFP scope (amber = target).

What "focal plane" actually means

Inside a variable scope, the reticle is placed at one of two spots relative to the lenses that do the zooming (the erector system). Put it in front of them and it is in the first focal plane; put it behind them and it is in the second. That single design choice decides whether the reticle appears to change size as you turn the magnification ring, and that in turn decides whether your holdover marks can be trusted at any zoom.

First focal plane (FFP)

In an FFP scope the reticle sits in front of the magnification lenses, so it scales up and down with the target image. The practical payoff is huge for precision work: because the reticle and the image zoom together, the spacing between the hash marks (the "subtensions" you use for holdovers, wind and ranging) stays mathematically correct at every magnification. You can range a target at 12x, hold wind at 20x, and the marks mean the same thing.

Second focal plane (SFP)

In an SFP scope the reticle sits behind the magnification lenses, so it stays the same visual size no matter how far you zoom. That makes it clean and easy to see at every power, and it keeps the scope simpler and cheaper. The trade-off: the holdover marks are only calibrated for one magnification, almost always the maximum. Use them at any other zoom and the distances they represent are off, so you either spin to the calibrated power first or dial your elevation turret instead.

FAQ

Is FFP or SFP better?

Neither is universally better; they suit different shooting. First focal plane (FFP) is better when you hold over or dial at changing distances and magnifications, such as long-range and PRS shooting, because the reticle measurements stay accurate at any zoom. Second focal plane (SFP) is better for hunting and fixed-distance shooting: it is simpler, usually cheaper, and the reticle stays easy to see at every magnification.

Does an FFP scope cost more than SFP?

Usually yes. Putting the reticle in the first focal plane and etching it in glass adds manufacturing cost, so at a given quality level an FFP scope typically costs more than the SFP version. For example, our value FFP pick, the Vortex Diamondback Tactical 6-24x50, sells around $280, while the budget SFP Vortex Crossfire II 3-9x40 is about $119.

Can you use holdover marks on an SFP scope?

Yes, but only at the magnification the reticle was calibrated for, which is almost always the maximum zoom. At other magnifications the SFP holdover marks no longer match true distances, so you either zoom to the calibrated power first or dial the turrets instead.

Which focal plane is better for hunting?

For most hunting, second focal plane (SFP) is the better fit. The reticle stays the same crisp size at every magnification, so it is always easy to see, the scope is simpler and lighter on the wallet, and typical hunting shots do not require precise holdovers at varying zoom. Both of our 3-9x40 hunting picks, the Crossfire II and Leupold VX-Freedom, are SFP.

What is the difference between first focal plane and second focal plane?

In a first focal plane (FFP) scope the reticle grows and shrinks with the image as you zoom, so its hash marks measure true distances at every magnification. In a second focal plane (SFP) scope the reticle stays one visual size no matter the zoom, so it is always easy to see but its holdover marks are only accurate at one magnification. FFP suits dialing and holding at long range; SFP suits simple, fixed-distance hunting.
